Application filed April 23, -191542, Serial No. 692,610. Renewed May 23,1914:. y Serial No. Momma To all whom it ma? concern.'

Be it known t at I, SOLOMON H. GOLD- nnc, a citizen of the UnitedStates, residing in the city of Chicago,'county of Cook, and State ofIllinois, have invented certain new and useful Improvements in PreparedRoofing, of which the followingis a specification.

rI`his invention relates to im rovements in prepared roofing and has forits salient 0bject to provide a roofing comprising essentially aflexible foundation, a granular facing, an intermediate binder coat anda skeleton form upon the upper surface of the binder to provide animproved roofing of the character referred to in which the granularfacing is applied in symmetrically arranged designs of any desiredcontour, such designs being spaced apart by a skeleton form forming partof the roofing; to provide an improved process of making a roofing ofthe character referred to which consists in applying a binder to aflexible foundation, securing a skeleton form to said binder andapplying a granular facing to said binder, said facing adhering to thespaces between the outlines of said form, but not to the outlinesthemselves, and in general to provide an improved product and process ofthe character referred to.

rIhis invention relates to the matters hereinafter described and moreparticularly pointed out in the appended claims.

In the drawings-Figure l is a top plan view of my improved roofing; Fig.2 is a transverse sectional view of the same; lFig. 3 is a view of theskeleton form taken by itself.

Referring to the drawings: 1 designates the flexible foundation, whichmay be of felt or analogous material. 2 the binder, which may be abituminous or asphaltic composition. 3, the skeleton form which may bemade of paper, wood pulp, light wood or other similar flexible material.

4, designates as a whole the granular facing, which may be of crushedgravel, crushed rock, crushed stone, crushed tile, minute pebbles orother similar granular substance, which is arranged upon the face of theroofing in symmetrically arranged designs, 5, 5, which in the presentinstance are shown as taking the form of shingles, so that the roofing'will represent a shingled roof.

Iam aware that heretofore many attempts have been made to make preparedroongs the face of the roofing. No roofing however,y as far as I amaware has ever been made in which the facing has been applied in thenovel way of the present invention.

The important feature of the invention consists in applying a skeletonform to the blnder, while' the latter is hot so that the form willadhere rigidly in place and then applymg over the` form a granularfacing of thecharacter referred to, which .granular facing fills up thespace between the outlines formed, but does not stick or adhere to theoutline of the form itself; the result is that the upper surface of theroofing has a plurality of symmetrically arranged granular designs, eachof which is surrounded by the corresponding outline of the skeletonform. 'Ihe form may be made of the same color as the binder beneath asfor example, if the binder is of black bituminous chary acter theskeleton may be colored the same or the skeleton form may be colored asdesired or it may be made more pr less transparent so' that the binderwill show through from beneath after the facing is applied.

'Ihe process may be carried out as follows: A web of felt or otherflexible mate rial is fed through a kettle or vat of hot bituminous orasphaltic binder so that the felt becomes saturated with the binder, andthereby water-proof; the saturated felt may then be fed through a secondkettle or vat containing a hot bituminous or asphaltic composition so asto applyba binder to the upper surface of the flexible foundation.

'After the binder is applied the skeleton form is fed to the face of thebinder and applied to the surface of the same in such a way that theform will lie flat and evenly over the upper face of the binder. 'Iheform will undoubtedly be more or less embedded in theho't face of thebinder and is thus permanently secured thereto when the binder cools,and sets. Immediately after the form is applied to the b inder and'while the latter is still hot; the partly prepared roofing may be fedbeneath suitable hopper or other feeding devices, by which the granularfacing may* be fed to the uppeni face of l the roofing in desired andregulated quantiand accordingly the latter is applied only in sminetrical designs spaced between the outllnes of the form.

The invention is not limited to the details of construction shown exceptas set forth in 10 the appended claim.

I claim as my invention:

As a new article of manufacture, prepared sheet roofing consisting of abacking sheet of pliable absorbent material having 15 its upper surfacecoated and impregnated with bituminous or analogous cementitious,Waterproof, sticky substance, an open-work pattern of material havingnon-adhesive upper surface, adhesively applied to the up er surface ofsaid backing sheet, and a sur acing of comminuted material adhesivelyapplled to, and covering the areas of the surface of the backing sheetexposed through said open-Work pattern, but leaving the latter uncoatedby said comminuted material.
